意义: 林业上常用适地适树这句话。造林前,首先要鉴定土地的适应性,然后选择适当的造林树种,这是直接影响林业增产的重大技术问题。就鉴定适地的这个问题来说,以往都是从气象、土壤、地形、地质等方面来加以探讨。树木的生长,就是这些因素综合作用的结果。但是,影响生长的环境因素是很多的,如果不能全部加以考虑,就无法得出正确的结论来。现实的问题,是要把这许许多多的因素加以整理,从而找出其中最主要的因素来。但是,哪些因素是主要因素呢?这需要根据地区和树种的不同,因地制宜地来加以考虑。本林业试验场,在数理统计研究所的协助下,应用分析法解决了这个问题。即应用电子 Significance: Forest suitable for tree planting this sentence. Before afforestation, we must first identify the adaptability of the land, and then select the appropriate afforestation species, which is a major technical issue that directly affects the increase of forestry production. In terms of the identification of suitable places, the past, from the meteorological, soil, topography, geology and other aspects to be explored. The growth of trees is the result of the combined effect of these factors. However, the environmental factors that affect growth are many and if not all can not be concluded correctly. The realistic problem is to sort out so many factors to find out the most important factor among them. However, what factors are the major factors? This needs to be taken into consideration according to the localities and tree species. The forestry pilot site, with the help of the Institute of Mathematical Statistics, applied analytical methods to solve this problem. The application of electronic
